Fly commercial to Kangerlussuaq. Rent a twin otter and fly to the ice sheet. Alternatively, get a job with the NSF research station and let them pay the transport!
It's cold! -40f/c is typical.... dress for the weather and prepare your camera and gear to take the punishment.
Ice crystals in the air form halos and arcs reflected by sunlight or in this case moonlight. This remarkable moment in time revealed common and rare optics. There are three complete halos -22 degree, 46 degree and a parhelic circle circling the sky... wonderful. There are numerous arcs including a rare Wegner Arc. A bonus is the slight aurora right of the moon. One of those times I will never forget.
